The Dialog stuck pipe log service uses a sonic measurement to provide an evaluation of a stuck pipe string. This service can be performed through drill pipe, casing or tubing to identify problem areas. Similar to conventional cement bond log measurement, high amplitude measurements indicate free pipe and low amplitude measurements indicate stuck pipe.

The stuck pipe log service is unique from the free point service because the stuck pipe log service may be used to determine multiple stuck points throughout the well whereas the free point service can only identify the shallow most stuck point. The stuck pipe log service gives additional information that allows an informed decision to be made as to how best proceed in the pipe recovery operation.
